I just changed my belt and in the process noticed the tensioner is off axis like a bearings gone or something. It off to one side under tension. Since I've never seen one off I was wondering if someone could tell me what goes wrong with these things. To get it off is it just that one center tork bolt? What all can ya'll tell me about this? thanks! 160k miles

easy peazy with a t50. replacement has a longer arm but same belt length. it orients a little different with 2 nub tabs that fit into corresponding holes in the mount. old tensioner kind of hollow in the middle...center relied on the nubs and just the head of the bolt. new part has support total length of bolt which makes more sense to me.

Another option - the later trucks have a dual-pulley tensioner that takes the place of our tensioner and the ribbed idler that's next to it. The pivot point is between the two pulleys, so it's less likely to go off-kilter like yours has. There's a TSB that shows how you can modify the bracket on our trucks to accomodate this tensioner.

Is this an easy upgrade to do? My tensioner is worn so that the pulley is no longer aligned and don't mind upgrading if it is not too much work.

Thanks!!

I envy those that know exactly which modification to make and in the most logical of sequences. But not enough to trade for my meanderings and misfires.
